1. A system comprising:
a plurality of parallel-connected photovoltaic strings, each photovoltaic string comprising:
a photovoltaic string having a series-connection of photovoltaic panels; and
a voltage-compensation circuit configured to produce an output power having an adjustable compensation voltage; and
a controller configured to:
monitor power and adjust the adjustable compensation voltage of each voltage-compensation circuit until a net total power is maximized;
wherein a plurality of first values are the adjustable compensation voltages for each of the voltage-compensation circuits,
wherein a second value is a minimum compensation voltage of the adjustable compensation voltages; and
for each adjustable compensation voltage, adjust the adjustable compensation voltage to a new voltage value, wherein the new voltage value is the second value subtracted from the first value.
